2014. W205, C Class C220. Diesel Blutec Automatic Saloon.
I have been trying to reset the service light on my 20ne14 c class W205, following instructions on youtube, ie. close doors & boot/bonnet turn key to position 1 scroll to trip on display, press ok. button and call accept button simultaneously. But nothing happens, What else should I do ?

Did you go to the Assyst plus bit first? There’s a few on YouTube , the Autologic one seems to go into more detail...
I haven’t done this myself by the way, just googled as you’ve done so apologies if we’re covering old ground

I'd have thought there is a detailed method shown in the user manual that should have been supplied with the car.

I'd guess the manual just says drive to nearest Mercedes dealer :D .......
mine does for the simple task of adjusting the headlamps for use in Europe. :eek:

Exactly- these are the bits they don’t want you doing yourself....

also some of these online guides make it look like it will work first go but in my experience it wont , tried doing my 221 and it refused point blank 6 times in a row , left it and tried again the day after and bingo ! reset first try

If its like mine, sometimes it works, sometimes it doesn't. Like yours, keep trying and it eventually changes. I found 2 different methods on line. The one that works is somewhere between them.:confused::confused::confused:
